We use the Vultr API to check which packages are available in which locations.
For example, the 96 GB plan only shows up in Toronto and Chicago:
Unfortunately, the $2.50 and $3.50 plans are not listed in their API. As mentioned in their documentation: Note: The $2.50 sandbox and $3.50 plan are not available in the API. That’s why we had to add them manually to our website, and since we can’t check availability, we added them to all locations.
At the moment, they only seem available in Atlanta. I’m checking with Vultr whether they can add these plans to the API so I can check which locations they are available in, but it’s unlikely.
